[Asterisk-Users] call-waiting caller-id

[Steve Dolloff]

Are there any known issues with call-waiting caller-id for SIP?

Caller-ID on the first call works fine, but when the second call comes
in, I hear the interrupt tone, but the caller-id doesn't display
anything.

I have tried this with the Cisco ATA and the SPA-2000.  I have also
tried two different phones to verify that it wasn't something specific
to the phone.

Thanks,

Stephen
